the word is a modern english compound adjective. 'university' originates from the latin 'universitas', meaning 'the whole, a corporation', which evolved to denote a community of teachers and scholars. 'train' comes from the old french 'trainer', meaning 'to drag, draw', which developed the figurative sense of 'to instruct or guide'. the suffix '-ed' is a native english formative used to create adjectives meaning 'having the characteristics of'. thus, 'university-trained' literally describes someone who has been 'drawn or instructed by the university community', concretely meaning having received a formal higher education.

Structure: university + train + ed university (latin, noun base meaning 'the whole, a corporation') + train (latin via old french, verb base meaning 'to draw, drag, instruct') + ed (old english, suffix forming adjectives from verbs or nouns, indicating a state or characteristic)
